Blanca - Enrique III no mark

Enrique III earned the epithet "El Doliente" — the Sufferer — for the chronic illness that plagued his entire reign, leaving him so physically debilitated that contemporaries questioned his capacity to govern. He ruled nonetheless, and these blancas were among the first systematic attempts to stabilize Castilian billon coinage after the monetary chaos of his father Juan I's reign, which had flooded the kingdom with debased vellón of wildly inconsistent fineness.

The absence of a mint mark complicates attribution; multiple royal mints operated concurrently under Enrique III, and unmarked pieces remain unassigned to a specific facility.
